Primary diffuse large B-cell lymphoma of the kidney: A rare case report and review of literature.

INTRODUCTION AND IMPORTANCE: Lymphoma can either be Hodgkin or non-Hodgkin (NHL) with diffuse large B cell lymphoma (DLBL) being a type of the latter with an aggressive behavior. Although it is common for NHL to involve the kidney in its advanced stages, disease that primarily originates from the kidney is rare and therefore poses a diagnostic challenge. CASE PRESENTATION: We presented a case of NHL that was initially thought to be Renal Cell Carcinoma (RCC) but later confirmed histologically to be diffuse large B cell Lymphoma. The patient was kept on doxorubicin, cyclophosphamide and dexamethasone. However, on day five of the treatment he succumbed. CLINICAL DISCUSSION: Lymphoma can be broadly grouped into Hodgkin and non-Hodgkin Lymphoma. Primary kidney lymphoma accounts for <1 % with non-specific symptoms hence can be challenging in the diagnosis. Biopsy yields in the diagnosis and management is primarily chemotherapy. CONCLUSION: This case reminds health care professional on the possibility of having primary Lymphoma of the kidney in a patients with renal mass. Treatment of lymphoma is different from RCC, a common renal malignancy in adult. Therefore, tissue biopsy for definitive diagnosis is mandatory before initiation of treatment.

Giant perineal epidermoid cyst in adult man: a rare case report and review of literature.

An epidermoid cyst is a common benign cutaneous mass that mostly occurs on the neck, face and trunk. The majority of epidermoid cysts are small and asymptomatic with the giant perineal epidermal cyst being rare and more liable to develop complications such as malignant transformation. The treatment of an epidermal cyst involves total excision of the cyst along with its wall to prevent recurrence. We present an unusual case of a giant perineal epidermal cyst in a 52-year-old male.

Concomitant squamous cell carcinoma of the bladder and renal tuberculosis: A case report from northern Tanzania.

Concomitant squamous cell carcinoma (SCC) and renal tuberculosis (TB) are a rare presentation. It is associated with poor prognosis and poses a challenge in the management. To the best of our knowledge, we present a challenging first document case of locally advanced SCC of the bladder with coactive renal tuberculosis.
